The purpose of this book is to provide a technically sound method, of sufficient accuracy, to make valid thermal performance studies of water cooling towers. Over twenty years ago a major industrial cooling tower manufacturer made a limited publication of a book “Cooling Tower Performance”, generally known as the “Black Book”. This was a collection of curves relating the variables which affect water cooling tower performance to a common index. This index provided a characteristic, a “degree of difficulty”, for the various combinations of cooling ranges, approaches, wet bulb temperatures, and water-to-air loadings. Although it was a major contribution to the art, the “Black Book” was not generally available, and its accuracy was decreased by simplifying assumptions made to facilitate calculations and the plotting of data, both of which were done by hand. As a service to the industry, and in consideration of a real need for a dependable generalized method for evaluating cooling towers which is simple to use, the Cooling Tower Institute has published this book, destined to be known in the trade as the “Blue Book”. Many ways of calculating cooling tower performance have been proposed and published in the past, however, the theory' which is the basis of this publication is the one generally accepted in the industry as being the most technically correct and accurate. The use of this theory' involves integration procedures that can become cumbersome when it is necessary to determine several factors or points. Therefore these integrations have been made over limits that encompass all normal operating conditions encountered in cooling tower work, and are presented in this publication in curve form in order to facilitate handling and rapid calculation. This book is applicable for use in designing cooling towers, for analysis of test data, and for prediction of performance with changes in operating conditions. It enables the evaluation of the performance of a given cooling tower, within reasonable operating limits, without the necessity of original performance curves. It also allows prediction of performance over a much broader range of operating conditions than the usual performance curves. Curves of this same nature, using the same performance calculation method, have been published by others. However in every case the utility of the curves has been reduced appreciably by inaccuracies in calculations and drafting. Maximum accuracy and consistency have been obtained by use of a computer for making calculations and plotting the curves in this book. The utility of these prior publications has also been limited by insufficiently broad coverage of the operating variables of wet bulb temperature, range, approach, and liquid-to-gas ratio. This publication has broadened the coverage to include all normally encountered conditions of cooling tower operations and has added sufficient curves to minimize the necessity for interpolation Tambien conocido como LIBRO AZUL DE TORRES DE ENFRIAMIENTO, COOLING TOWER INSTITUTE - CTI (ahora esta institución se llama COOLING TECHNOLOGY INSTITUTE - CTI) ATENCION: EL LIBRO ESTA INCOMPLETO, NO TENGO ACCESO AL LIBRO COMPLETO, SI TINES EL LIBRO COMPLETO ESCANEALO Y SUBELO A INTERNET, EL CONOCIMIENTO DEBE SER LIBRE ACA PUEDES DESCARGAR EL DEMO DE CTI ToolKit, este programa te dara la grafica de curvas de torres de enfriamiento para un rango limitado de temperaturas. tambien puede ayudarte: https://cti-marketplace.myshopify.com/products/cti-toolkit-version-4-0-demo
